Vaadin Flow How to control focus TextField in Grid?

Question

As my first question

SerializableFunction<MyItem, TextField> function = item -> {
TextField tf = new TextField();
tf.setValue(item.getMyValue());
tf.addValueChangeListener(e -> item.setMyValue(e.getValue()));
return tf;
};
ComponentRenderer<TextField, MyItem> cr = new ComponentRenderer<>(function); 

I found another problem that I found no way to indicate focus of textField on SelectChange event of Grid.

I found that when add a new record , the SelectChange event is prior to the create of textField.

and seems vaadin has no Row Concept ?

First thought that springs to mind: add a class variable that keeps track of the latest selected item (updated when the selection change listener is triggered), and check your item against that in your function . (And maybe also another class variable for saving the previously styled TextField, so that you can remove the selection styling too.)
